An eyebrow is an area of short hairs above each eye that follows the shape of the lower margin of the brow ridges of some mammals. In humans , eyebrows serve two main functions: first, communication through facial expression , and second, prevention of sweat, water, and other debris from falling down into the eye socket.
The brow ridges are often not well expressed in human females, as pictured above in a female skull, and are most easily seen in profile. The brow ridge, or supraorbital ridge known as superciliary arch in medicine, is a bony ridge located above the eye sockets of all primates and some other animals.
The glabella, in humans, is the area of skin between the eyebrows and above the nose. The term also refers to the underlying bone that is slightly depressed, and joins the two brow ridges. It is a cephalometric landmark that is just superior to the nasion. [1]
The muscle acts in tandem with the orbicularis oculi muscle.The corrugator supercilii muscle acts upon the skin of the forehead superior to the middle of the supraorbital margin, [1] drawing the eyebrow inferomedially to produce vertical wrinkles of the forehead [3] just superior to the nose. [1]
It arches transversely below the superciliary arches and is the upper part of the brow ridge. It is thin and prominent in its lateral two-thirds, but rounded in its medial third. [3] Between these two parts, the supraorbital nerve, the supraorbital artery, and the supraorbital vein pass. The supraorbital nerve divides into superficial and deep ...
